What is Memory_inject.exe process?

Memory_inject.exe is a malicious process created by coin miner virus

As I have actually specified in the previous paragraph, Memory_inject.exe is a coin miner trojan virus. The names of the executive file may be different, however, the effects are generally the identical. Since coin miners focus on cryptocurrency mining, they utilize all available hardware power of your desktop to conduct this process. This malware does not care about the fact that you may want to use your machine for other tasks – it will constantly use over 80% of your processor power.

Memory_inject.exe Windows Process

Memory_inject.exe – Extremely high CPU as well as GPU usage

Besides CPU usage, some of the coin miners additionally use GPU power for their operations. In that situation, you will probably struggle also to see the mouse arrow moving – GPU is often utilized on 100%. It is not as essential as processor for system work, so Memory_inject.exe coin miner viruses do not waste time on trifles and utilize all of it. It often can lead to sad effects.

Shortly about cryptocurrency mining

Cryptocurrency mining means the action of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this action takes a lot of calculations, a strong machine is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining farms usually consist of dozens of graphic cards to complete their task efficiently. Such computer systems are not usable for “usual” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

  • Microsoft Defender is stopped;
  • CPU and GPU is loaded at 80-90% exactly after the system start
  • Cooling fans are running at high speed and create a lot of noise
  • A single process in Task Manager consumes all CPU and GPU power
  • How dangerous is the Memory_inject.exe miner?

    Coin miners does not deal damage to your files. However, they make a lot of unpleasant things with the whole system

    Firstly, Memory_inject.exe malware makes your PC overloaded. It is unable to run your applications anymore, because all processor power is consumed by a virus. That malware does not care for your necessities, all it focuses on is generating profits on you. Even if you are patient, and you waited until browser is open, you will likely suffer from exceptionally sluggish efficiency. Pages will open for years, any kind of logins will likely take about a minute – just a headache for a person who does a job online.

    “Visible” harm is not a solitary bad thing coin miners perform to your system. Memory_inject.exe coin miner also deals damage to your OS. To carry out all malevolent operations properly, it ruins the protection components of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent detection. If you check the HOSTS file, you will likely see a number of new entries – they are brought in by this coin miner to connect your computer to a malicious mining network. All these changes shall be thrown back to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak power for long times can cause damage to your machine and raise power bills. Hardware components are designed to easily get along with high load, but they are good with it only in case when they are in a good shape.

    Small and covered processor cooling system is hard to damage. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily cracked if affected while running, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the very high load caused by Memory_inject.exe miner can easily lead to GPU failure3. GPUs are also tend to have fast wearing when used for crypto mining. It is likely a bad case when the performance of your GPU decreases on 20-30% just after 1-2 weeks of being used in such a way.

    How did I get Memory_inject.exe coin miner virus?

    Coin miners are spread through different ways, but their main sources are malicious banners and programs from dubious sources

    Coin miners are the most prevalent malevolent programs among “severe” malware. Adware often functions as a carrier for Memory_inject.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any type – yet another adware, spyware, rogue or backdoor. But the statistics say that around 30% of all malware spread through the malevolent banners are coin miners – and Memory_inject.exe is just one of them.4

    The example of malicious banners you can see in the Internet

    An additional way you could get this thing on your PC is by downloading it from the suspicious site as a part of a program. Users that spread hacked versions of popular programs (which do not demand the license key) have small chances to make money. For this reason, there is a huge lure to add malware to the final package of the hacked app and receive a coin for every setup. Before criticizing these individuals for hacking and malware distribution, ask yourself – is it alright to avoid purchasing the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much bigger sum for antivirus software as well as new parts for your PC.

    How to remove the Memory_inject.exe miner from my PC?

    The best way to get rid of this coin miner virus is to use anti-malware software

    Eliminating such a virus needs the use of specific program. Appropriate anti-malware program must have high performance at scanning and be lightweight – in order to make no problems with utilization even on weak computers. Furthermore, it is better to have proactive protection in your security tool – to stop the virus even before it starts. Microsoft Defender does not have these functions for various factors. That’s why I’d advise you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a perfect choice that fits all of the specified features.5

    Prior to the malware removal, it is important to reboot your operating system into Safe Mode with Networking. Since Memory_inject.exe miner consumes a lot of CPU power, it is needed to stop it before launching the security program.
